When Masachika opened his eyes after reflexively wiping his face with his hands, he saw Yuki lying face up in a plastic pool pointing a water gun at him. “...Hey, seriously, what are you doing?” Masachika’s cheeks contracted as he asked his sister again, who was secretly smiling at him. Then, Yuki smiled and looked up at the summer sky, playing with her water gun and acting calm. “Don’t worry about it... It’s just a bit of my innocence coming out.” “Innocence, huh.” “Yeah, my adrenaline.”[1] “Don’t say it like it’s adrenaline.” While throwing a tsukkomi and looking at her, Masachika approached Yuki and stroked her head. “Yes, serotonin.” “Wuaaaahh, happy hormones are being released〜... Wait, what the hell am I doing?” “Don’t suddenly put on a serious face like that. I’m the one who wants to ask what you’re doing here.” “What am I doing, ugh, my head...!” “Have you been brainwashed? Let’s quickly remember again.” “Gununu... Haa! ...At this point, I started to remember...that this world was the world of the otome game I played before my death.” “Didn’t anyone tell you to remember your previous life?” “Suou, Yuki...? Ugh!!! Impossible! I was reincarnated as an evil noble girl?!” “I’m worried that you really are possessed by an evil demon.” “I just remembered...that my brother and I are evil characters who always play pranks on the heroine.” “Don’t tell me the main heroine is Ayano.”
